To all whom it may concern:

Be it known that I, JOHN ALLENsoN, a citizen ofthe United States, and a resident of the city of Grand Junction, county of Van Buren, and State of Michigan, have invented certain new and useful Improvements in Water-Tanks, of which the following is a specification.

My invention relates to improvements in water tanks designed for use especially in dwelling houses in the rural districts, and has for its object the production of a tank of this character adapted to accommodate both rain and hard water and so arranged as to permit of the use of either with equal facility. A further object is the production of a tank of the character mentioned which will be of concrete construction, and in which the pipe connections cooperating therewith will be so arranged as to be adapted to yield to allow for expansion or contraction of the concrete walls.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in which,

Figure 1 is a front elevatio-n of a water tank embodying the invention, the same be ing shown located in the basement of a building, the latter being shown in section,

Fig. 2, a top plan view of the tank, showing the surrounding building walls in section,

Fig. 3, a side elevation of Fig. 1,

Fig. 4, a vertical transverse section through the tank,

Fig. 5, a detail section through one of thev manholes which communicate with each chamber of the tank,

Fig. 6 a rear elevation of one of the manhole covers,

Fig. 7 a detail section illustrating the method of fastening of' the pipes in the concrete walls of the tank, and

Fig. 8 a top plan view of the construction seen in Fig. 7 with the tank wall omitted.

The preferred form of construction as illustrated in the drawings comprises a concrete tank 10 substantially rectangular in form, in which are provided two independent chambers 11 and 12, the former being adapted to accommodate rain water, and the latter hard water.

Communicating with the bottom of chamber 11 is a combined supply and outlet pipe 13, said pipe 13 leading horizontally outwardly from under the tank and then up-k wardly, communicating at its upper end with an exteriorly projecting pipe 14 which communicates with an upstanding pipe 15 adapted to communicate with the roof of the building or other means of rain water collection employed in connection with the building so that any rain collected will be delivered to the pipe 15, and thence to the pipes 14 and 13 into thechamber 11. A check valve 16 is interposed in the pipe 14 which permits of flow of the rain water only in a direction toward the tank. At the lower end of the pipe 15 is provided a plug or stop-cock 17 for draining the water from pipes 14 and 15 in cold weather. From the upper end of the pipe 13 also leads an outlet pipe 18 which is adapted to communicate with any place where it is desired to deliver the water.

In a similar manner, a pipe 19 leads from the bottom of the hard water chamber 12, the pipe 19 being connected with a supply pipe 20 which is adapted to communicate with a pump or other source of hard water supply, through the medium of which hard water may be supplied to chamber 12. A check valve 21 is interposed in the pipe 20 which permits of flow of hard water through the pipe 20 only in a direction toward the tank. The pipe 19 is extended upwardly as clearly seen in Fig. 3, the upper end thereof communicatingwith a pipe 22 adapted to lead to any location where it is desired to use the water. The upper ends of pipes 13 and 19 are connected by a pipe -23 in which is interposed a manually adjustable valve 24. The valve 24 will normally be closed, but through the provision thereof, in the dry season, water from the hard water chamber may be supplied to the rain water outlet pipe 18, as will be readily understood.

Leading from the upper ends of chambers 11 and 12 are pipes 25 and 26-which project throughthe bottom of the tank, thence under the same and thence upwardly, each of said pipes being connected at its upper end with a pressure gage 27. Also connected with the pipes 25 and 26 is a compressed air supply pipe 28 through the medium of which compressed air may be supplied to the chambers 11 and 12 in order to effect automatic discharge of the water from said chambers when the pipes 18 and 22 are open. Emergency exhaust valves 29 interposed in pipes 25 and 2G adjacentthe pressure gages 27 insure against too great a pressure being" created in the tank, the valve mechanisms 29 being adjustable in nature and adapted to automatically operate to exhaust air from said tank chambers in the event of a predetermined pressure being reached. The pipe 28 will also serve as an exhaust pipe in order to relieve the pressure in chambers 11 and 12 in the introduction of water thereinto, said chambers being closed chambers; it is of course apparent that air must be exhausted therefrom in order to permit of the entrance of the water. After the tank chambers have been supplied with water, pressure will of course be introduced thereinto through the medium of the pipe 28, as will be readily understood. In order to lock the pipes against relative movement in the tank walls through which the same project, each pipe which passes through the concrete tank wall, is provided with a flange 3() which is suitably secured to the pipe, as clearly seen in Figs. 7 and S. Said flange 30 will be embedded in the concrete in the molding of the tank, and thus will serve to effectually lock the pipe against movement.

Formed in the front side vof the tank are manholes 31 which communicate with chambers 11 and 12, said manholes affording means whereby said chambers may be entered in order to repair or clean out the same. Said manholes are normally closed by covers 32 from which project threaded stems 33, as seen in Fig. 5. Each of the stems 33 is embraced by a resilient yoke or arched member 34 which engages at its ends against the outer side of the tank wall, the central portion of said member being engaged by a hand screw 35 which is threaded upon the outer end of the corresponding; stem 33. The covers 32 will thus be securely held in closed position, and if desired the same may be additionally sealed by any suitable means to positively insure against any leakage. Each cover 32 carries a water gage 3G whereby the level of the water in the tank chambers may be ascertained.

1With the construction set forth, it will be seen that a water tank is provided in which rain water and hard water may be accommodated and in which either may be withdrawn with equal facility. By extending the pipes 13 and 19 outwardly and upwardly before connection of the same through the medium of the pipe 28,' considerable give or yielding is permitted in the connect-ion of said pipes which will allow for expansion or contraction of the concrete ,without affecting the connection of said pipes.

The' same holds true with regard to the pressure pipes 25 and 26 which also extend outwardly and upwardly before connection of the same with pipe 28.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to tho precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having described my invention what I claim as new and desire to secure by Letters Patent is:

1. A concrete water tank having two independent chambers, one for rain water and one for hard water; an exteriorly projectingsupply pipe communicating with said rain water chamber; an outlet pipe communicating with said supply pipe; a supply pipe communicating with said hard water chamber; an outlet pipe communicatingwith said hard water supply pipe; a valved communication between said supply pipes; and means for introducing air into or exhausting the same from each of said chambers, substantially as described.

2. A concrete water tank having two independent chambers, one for rain water and one for hard water; an exteriorly projecting supply pipe communicating with said rain water chamber; an outlet pipe communicatingjwith said supply pipe; a supply pipe communicating with said hard water chamber; an outlet pipe communicating with said hard water supply pipe; a check ,valve inV each of said supply pipes, a valved communication between said supply pipes; and means for introducing air into or exhausting the same from each of said chambers, substantially as described.

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

JOHN ALLENSON.
